For ICC Cricket World Cup operations manager Anthony Crummy, events like the blue ribbon of international cricket were occasions where the unexpected could happen and the old saying "beware the underdog" was very much the case.
Teams like Afghanistan, who take on the Black Caps at McLean Park next month, and the United Arab Emirates, who also have appointments here with Pakistan and the West Indies, could not be underestimated, he said.
"You just have to look at the past ones - every World Cup has a giant killer in there somewhere and someone gets a big fright."
Afghanistan, he said, were a "very good side" and no one they faced would take them lightly.
Mr Crummy said, at this stage, the Napier match was the only pool match being played by the Black Caps which had not sold out, but added tickets sales were strong.
